Abstract

Thin films of YBa2Cu3O7-x have been obtained on NdGaO3 substrate by pulsed laser deposition with an excimer KrF* ((lambda) equals 248 nm, (tau) FWHM>= 20 ns laser source from a stoichiometric target. In the present paper we report details of the technology of pulsed laser deposition of high-temperature superconductor thin films, substrates' requirements and high-temperature superconductor thin film characterization. The study of some parameters' intercorrelations for optimization of the technology of the pulsed laser deposition of high-temperature superconductor thin films is also analyzed. Moreover, the contacting technology and techniques of characterization are described.
